What information does the show interfaces command provide?

• A. Interface information and packet flow counts
• B. IPv6 neighbor discovery details
• C. The MAC address table only
• D. The current routing table

Answer: (A)

The show interfaces command provides information about each network interface’s operational state and its traffic statistics. It shows whether the interface is up or down, basic settings like IP address, MTU, speed, and duplex, plus per-interface counters for packets received and transmitted, along with errors, drops, and other run-time statistics. This combination of status and packet flow data is what you’d use to assess interface health and monitor traffic.

Other options point to different data: IPv6 neighbor discovery details come from a command focused on neighbor cache entries, the MAC address table is shown by a command that lists learned MAC addresses, and the routing table is shown by a command dedicated to routes.
